Nissan Stanza 1986 car bucks and cuts out when accelerating

Suddenly the car lost power and bucked when accelerating. It won't start after it has cut out but will if it rests (so not the battery). Now can not drive at all but will start and idle. If accelerator is pushed down it does the same thing. Replaces all the spark plugs, wires and filters, checked all the fuses. There was no change in the problem after this tune up.

Something is wrong in your start circuit. From battery to ignition switch, and ending at the starter solenoid. You would have to start checking for where power is lost between the switch and the starter. If you have power to the starter solenoid on the small wire at the starter (can check with a test light while someone holds the key in start), then the starter would need testing.

have you checked the relay between the battery and the starter?i had a ltd 2 that suddenly refused to start after trying everything else it turned out to be a little black box(relay) on the fender well between battery and everything else!

not starting or turning over indicates towards multiple possibilities. It can
be issue with battery or weak battery. But if battery checks out ok, then it
can be starter issue or faulty alternator or problem with low fuel pressure or
no spark at spark plugs due to dirty spark plugs or faulty ignition
coil or injectors getting cracked or dirty and needs to be cleaned.

I had a turbo renault , I cranked the wastegate down to increase boost and had same problem.
There was a sensor that cut the ignition if the turbo was over pressuring. Was a pretty violent jerking, felt like it was tearing the engine mounts out.

my suspect would be the alternator at this point. an alternator can cause sudden stall out while driving. did the lights(headlight/dash light) dim out when you stalled? do they dim when you try to start it. the belts and fan is intact? i dont think it will show a code if its not getting any juice from alternator. it also could be ignition switch but i need this info first.
let me know
